JOHN D. BURTON, OF PITTSBURG, PENNSYLVANIA.

METAL ROOFING.

SPECIFICATION forming part of Letters Patent No. 406,024, dated July 2, 1889.

Application filed February 5, 1889- Serial No. 298,781. (No model.)

To all whom it may (JON-0877b:

Be it known that I, JOHN D. BURTON, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Metal Roofing; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to an improvement in sheet-metal roofing; and it consists in cutting sheets of metal into form and turning the edges and joining them together, as will hereinafter more fully appear, and as represented in tlie drawings.

To enable others skilled in the art to make and use my invention, I will describe its construction.

In the accompanying drawings, which form part of my specification, Figure 1 represents the roof of a building when the sheets and comb-piece are in position. Fig. 2 shows the manner of securing the sheets together.

In the drawings, A represents the form or shape of the sheets of metal, the upper portion of the sheets having the edges B turned over outwardly and the lower portion turned under or inwardly, the sheets being provided with nail-holes D.

In placing the sheets on the roof the lower edges of the first row of sheetsviz., those next the eaves of the building-are flattened out or turned down and secured to the timbers. The upper or outward-turned edges B then hook into the lower or innerturned edges (shown in dotted lines in Fig. 2) ol' the next course of sheets, and so on until the comb-piece is reached, When the angleshaped piece E is placed in posit-ion over the upper edges of the top course of sheets. The sheets are held to the shooting by driving nails into openings D.

\Vhen the sheets and comb-piece are in position, the roof Will present a neat appearance and be perfectly water-tight.

Having thus described my improvement, what I claim is A metal roofing consisting of sheets of metal having their upper edges turned over upon themselves, forming a parallel fold and meeting in a point, and their lower edges turned under upon themselves, forming a parallel fold and meeting in a point, having the squared corners and the cut-out portions in the metal of the upper turned-over edge to allow the entrance of the fastening devices, substantially as described.

I11 testimony whereof I have hereunto set my hand this 26th day of April, A. D. 1888.
